So, what, specifically, do you believe about the Bible? That it contains truth? Some truth, all truth? That's it's a collection of interesting stories? What specific truth did Mohammed teach about the Bible? Do you believe Adam literally existed and that angels literally exist and bowed to him?
I believe that dissecting the books and trying to argue they are untrue for any number of reasons both misses the point of the message and is almost always not factual anyway and merely shows a persons misunderstanding of it.
Thus, so far as I am able, I will defend the books by providing the proper context of what happened and any factual information I can. But I will not argue about whether something happened or not so far as our discoveries have no way of showing, because to do so misses the point entirely.
Thus, in answer to your question. I will say I believe Jesus was the messiah, that he willingly took this role, and that he died and was raised to heaven. Because I believe this i strive to live up to his example and direction to love, be tolerant, amd treat people as I wish to be treated whether I agree with their choices or not. I will not judge them or think badly of them, and will seek to make amends whenever I do since it will happen despite my best efforts. all this I will do because I do not miss the point of the message. I also believe that something bad will likely happen to those who have assumed the role of a messenger or Christ, as per Jesus stating it would. And that all religions following a man today are false. In the end, what I believe, is that people like you and I and others here who have renounced our religions because of their clear hypocrisies and lies will be saved, as well as all those who are in the religions honestly trying to find truth, as well as all those whomever else the judge finds is a good and righteous person, regardless of any errors they may have made.
and I believe this because it is, in fact, what the bible says - and, so far, the Quran as well.
